To all whom it may concern:

Be it known thatI, MARTIN JELALLA'N, a citizen of the United States,residing at the city of Cranston, in the county of Providence and Stateof Rhode Island, have invented certain new and useful Improvements inCombined Dirigible and Hydro Aeroplanes, of which the following is aspecification.

The object of the invention is to provide new and useful improvements inaerial apparatus of that class which are capable of traveling on land orwater, and to arrange the certain parts of the apparatus that the samemay be readily and safely operated and controlled, and arrange thepropellers so that the same will permit of obtaining the desired speedand to fully assist the gas bag in the lifting operation.

The object of the invention is to generally improve this class ofair-ship, and it consists in certain and special features ofconstruction and combination of parts, as here inafter described andclaimed.

A practical illustration of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference inclicate corresponding parts in all theviews.

Figure 1 is a side perspective elevation of my improved apparatus. Fig.2 is a transverse sectional detail View. Fig. 3 is a side perspectiveView, with the main plane removed. Fig. 4c is a top perspective view ofFig. 3 with the side extending planes of the car removed. Fig. 5 is aview of a looking device for the rudder. Fig. 6 is a side perspectivedetail view, of the winged device.

Referring to the drawings, numeral 1- designates a car which may beconstructed of a light and durable material, such as, bamboo or othersuitable material. The car --1 is provided upon the bottom with a springcushion landing device, which comprises a series of supports 2 extendingto a converging position having an integral collar -3 at the free endsthereof and also a shaft 5- extending therefrom. Said shaft 5 also hasan integral collar 5 at the free end thereof and said collar is designedto have sliding movement in a tubular member -6- which is looselymounted upon the free end portion of the shaft 5. An expanding coilspring -4. encircles said shaft having its ends jecting inwardly to thecar secured against said collar -3 and the fre6e end portion of thetubular member The tubular member -6 has an integral transverselyextending portion adapted to loosely support a wheel shaft 5*, saidshaft having a solid wooden wheel 6 secured at each end thereof. By thearrangement described it will be obvious that the apparatus will make aperfectly safe descension.

The car l is provided with windows 9 9 in both sides of the same for observation purposes. Extending from the forward end of said car -1- is afiat vertical rudder 10- which extends from the lower portion of atubular curved shaft l6 and is secured thereto. The shaft l6 is looselymounted upon a vertically arranged stationary pin 1l and pro- --1- fromthe central part thereof and also having a steerwh'ecl 28 secured at itsupper end; projecting forwardly from the forward end of the bottom ofthe car 1 is a supporting member -5 which is designed as a support forthe vertical stationary pin -1land the latter having its lower endrigidly connected thereto.

Extending transversely to the car behind the steer wheel -28- is anumber of seats 19 arranged upon a platform 17 fixed upon said platform17 is a rod 18 a foot operated rudder lock 17 mounted upon the centralportion of said rod 18 and having a coil pull spring connection -18*,18*- upon each side thereof; said coil pull springs 18*, 18* encirclethe rod --18 having one of their ends secured to the platform and theother ends attached to the lock -17-. A portion of a sprocket wheel 17is made fast to the tubular shaft 16 and adapted to receive the free endportion of the lock -l7 as shown in Figs. 4: and 5. This is illustratedin order to make clear that the operation of the rudder may becontrolled in a completely safe and successful manner.

Extending transversely to the car 1 behind the platform 17 is a shaft-17 provided with a revolving propeller 8 at each end thereof, andmounted upon said shaft 17 is a sprocket wheel 17* adapted to be drivenby a sprocket chain 23, running over a second sprocket TIE wheel 26mounted upon a central wing shaft 18 which is provided with a crank ateach end thereof. Mounted upon the central portion of the central shaft'l8 is a sprocket wheel 20 which is driven by chain 22 mounted upon amain sprocket Wheel l8 which is mounted upon a m'otor shaft l9 Alsomounted upon the I central shaft 18 is another sprocket wh'eel '2- whichcooperates with a sprocket chain l7 to drive a second sprocket wheel 16mounted upon a 1 shaft which is provided with a revolving propeller -8-at each end thereof.

like wing -31, which are made of closely woven fine wires 16 and canvassecured to the latter, and said wings -31 have their inner endspivotally connected centrally to the upper portion of said car 1 as at30, Each wing has a vertical supporting arm 29 arranged centrallybeneath the same, and said vertical supporting arm 29 has an eyelet atits lower end and loosely mounted upon the end portion of the centralshaft l8 which is provided with a crank at each end thereof. A flatcircular support -9 has a series of wing supports 11 11 encircling thesame their lower ends pivotally connected to said flat circular support9 as at 16- and the upper ends pivotally united to the transverse wingsupports -15, 15 The flat circular support 9 also has eyelets 11 11*'---upon the bottom thereof, and the upper end of said vertically arrangedsupporting arm 29 is pivotally connected thereto by a pivot pin 15 asclearly shown in F 6. The wing supports 1l 11 may be made of suitablewires other than woven yieldable material or pullsprings may be used ifdesired.

' Coil pull-springs l6 16 are arranged centrally upon the wings 3l, 3land have one of their ends secured to the free ends of the transversesupports 39, 39 and the other ends attached to the eyelets l6 l6integral with the wings 31,

31, and said pull springs are designed to facilitate the upward movementof the wings. By the arrangement described it will be clear that thewings -31, 31 re ciprocate or receive up and down motion in the mannerof the wings of a bird.

he central. crank shaft 18 also has an integral collar -l6 16 within andnear to each end thereof, and a threadedcollar secured at the free endsthereof in order to keep the vertically arranged supporting arms intheir normal position upon the end portion of the crank shaft '18.

Projecting outwardly from the central portion of the car -1 is a plane1l which extends outwardly from each side of the car and is directlybeneath the laterally extending wings i+31, 31-, and a Wire netting 9 issecured to said planes 1t, 1l and canvas is secured upon the netting.Secured beneath each of said planes 14, 14 are cylinders -15, 15 whichare provided with straps -9 9 for attaching to the-plane Said cylinders15, 15 are adapted to receive air under pressure therebyprovidingbuoyancy t0 the planes .14,

14 and to float upon the surface of the water when traveling through thewater.

The bottom of the car 1 is made of closely woven fine wires and alightWaterproof material secured to the latter.

Extending around the top of the car 1 is a series of vertical supports-34, 8%,

which support a main plane 37. The

wings 31 and the. revolving propellers 8- are located directly beneathsaid main plane 37, and when operating force the air directly beneaththe same, thereby assuring an unusual speed and considerable amount oflifting capacity. 4

. Projecting through said main plane 37 are vertical supports 34, 3l thelower ends of which are secured to the top of the car l and the upperends thereof connected to the supports 11, 11 which extendlongitudinally of the plane -37,

and said supports are adapted to support a gas bag 5 therebetween.

The gas bag 5 is provided with a series of integral straps 9 9 extendingtransversely to the same andv having their ends attached to the supports1l 11 which extend centrally to each side of the gas bag 5 Theflutilityof arrangingthe gas bag is that the same will assist in liftingoperation and also will prevent the apparatus from being tilted.

Ylhe operation of the device will be readily understood, and it'will beobvious that by the arrangement of the revolving propellers and thevertically reciprocating wings described the apparatus has unusualamount of speed and also lifting capacity, and all the constitutingparts of the device are readily and safely operable.

Thus describing my invention what I claim as new and desire to-secure byLet ters Patent is:
